My two sons are the ones who talked me into getting a metal detector to "search for treasure". My youngest one is now starting to show interest in going out himself. I wanted to practice retrieving targets with a screwdriver so I let him do the detecting while I dug. He managed to find 66 cents and a pin before the gnats got too bad for him. He was very excited. I'm not sure how someone would have gotten this pin and it's clearly not old. Interesting nevertheless.
